LP-1W4 Single Element Watt Transducer

The LP-1W4 single element watt transducer converts ac current and voltage signals into a bi-directional dc output signal proportional to the active power flowing in the circuit.

The transducer is designed for 3 phase 4 wire systems with a balanced load.

Ordering information: LP-1W4, inputs including CT & VT ratios, output, calibration, power supply.
Example: LP-1W4, inputs 250/5A 400V, output 0-10mA, 0-200kW, 230Vac supply

Note. The LP-1W4H pulse output version is no longer available.
